In the figure, Let R1 = 105 ?, R2 = R3 = 50 ?, R4 = 70 ?, and ? = 18 V; assume the battery is ideal.
What is the equivalent resistance of the network shown?
What is the current in resistor R1?
What is the current in resistor R2?
What is the current in resistor R3?
What is the current in resistor R4?

2,3, and 4 are iin parallel so
1/R = 1/50 + 1/50 + 1/70
R= 18.42 ohms
combine this with R1
R total = 105 + 18.42 = 123.42 ohms
things in series share current
so I total = I1
I1 = 18/123.42=0.146 A
V parallel = 18.42*0.146=2.69 V
things in prallel share voltage so
I2 = Vparallel/R2 = 2.69/50=0.0538 A
I3 = I2 = 0.0538 A
I4 = 2.69/70 = 0.0384 A
